CHAPTER 13
WORK-RELATED MUSCULOSKELETAL DISORDERS
LEARNING OBJECTIVE
At the end of the module, the students will have a basic understanding of various musculoskeletal disorders that are caused by occupational exposure to physical workplace risk factors. Anatomy of the muscular and skeletal systems is covered as well as injury and disorder prevention techniques.
INTRODUCTION
Musculoskeletal disorders are a broad class of disorders involving damage to muscles, tendons, ligaments, peripheral nerves, joints, cartilage, vertebral discs, bones, and/or supporting blood vessels. Work-related musculoskeletal disorder (WMSD) is a subcategory; these are injuries and illnesses that are caused or aggravated by working conditions. MSDs are not typically caused by acute events but occur slowly over time due to repeated wear and tear or microtraumas.
WMSDs are also known as cumulative trauma disorders (CTDs), repetitive strain injuries (RSIs), repetitive motion trauma (RMT), or occupational overuse syndrome. Examples of WMSDs include herniated disc, epicondylitis (tennis elbow), tendinitis, de Quervain's disease (tenosynovitis of the thumb), trigger finger, and Reynaud's syndrome (vibration white finger).
Researchers have identified specific physical workplace risk factors for the development of WMSDs: force, posture, compression, repetition, duration, vibration, and temperature. Exposure to these risk factors can result in decreased blood flow, elongation, compression, tears or strains to muscles, tendons, ligaments and nerves as well as disc or joint damage. When present for sufficient duration, frequency, or magnitude, physical workplace risk factors may cause WMSDs. In addition, personal risk factors, such as physical conditioning, existing health problems, gender, age, work technique, hobbies and organizational factors (e.g., job autonomy, quotas, deadlines) contribute to, but do not cause, the development of WMSDs.
Applying ergonomics principles to reduce a worker's exposure to the physical workplace risk factors decreases the chance of injury.
This unit is not designed to impart skills in the diagnoses of WMSDs, only occupational healthcare providers do so. This unit is a background in some of the more common WMSDs and explores anatomic features that are affected by WMSDs. It is written from the view point of an ergonomist and not a healthcare provider. For convenience, this chapter is divided into four sections:
· The musculoskeletal system
· Disorders of the
· spine
· upper extremities
· lower extremities.
THE MUSCULOSKELETAL SYSTEM
The musculoskeletal system's primary functions include supporting the body, allowing motion, and protecting vital organs. The musculoskeletal system is an organ system that gives humans the ability to move using their muscular + skeletal systems (musculoskeletal). The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton, cartilage (framework), musc.

Histology and physiology of muscle contraction
It explains the basic structure of muscles and how muscle works for contraction.
In this, Disorders of muscles are also mentioned.
Structure of muscle: A whole skeletal muscle is considered an organ of the muscular system. A muscle uses ATP to contract and shorten, producing a force on the objects it is connected to.
A muscle consists of many muscle tissues bundled together and surrounded by Epimysium, a tough connective tissue similar to cartilage.
The epimysium surrounds bundles of nerve cells that run in long fibers, called Fascicles.
These fascicles are surrounded by their own protective layer, the Perimysium. This layer allows nerves and blood to flow to the individual fibers. Each fiber is then wrapped in an Endomysium, another protective layer.
These layers and bundles allow different parts of a muscle to contract differently.
The protective layer surrounding each bundle allows the different bundles to slide past one another as they contract.
Properties of muscle contraction:
Excitability • the ability to receive and respond to stimuli.
Conductivity • The ability to receive a stimulus and transmit a wave of excitation (electrochemical activity)
Contractility • the ability to shorten forcibly when stimulated.
Extensibility • the ability to be stretched or extended.
Elasticity • The ability to bounce back to original length
Whether it is the largest muscle in your body or the tiny muscle, every muscle functions in a similar manner.
A signal is sent from the brain along a bundle of nerves. The electronic and chemical message is passed quickly from a nerve cell to other nerve cell and finally arrives at the motor end plate/ Neuromuscular junction.
This signal causes the myosin proteins to grab onto the actin filaments around them.
Myosin uses ATP as an energy source to crawl along the green filament, actin.
Many small heads of the myosin fibers crawling along the actin filaments effectively shortens the length of each muscle cell.
The cells, which are connected end-to-end in a long fibers, contract at the same time and shorten the whole fiber.
Here are the several disease related to muscles such as
myasthenia gravis, muscular dystrophy, atrophy, etc.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
